whats the worse that can happen??? ive just found out my chipped ecu was automatic and its in manual car p28-a52. ???

does it still matter if you put s300 on it.

i read a lot about people saying it will throw check engine light #19 on, but will anything else happen to it, like maybe not run right, ??

 

No, nothing will happen other than the CEL, but you could cut out the simple resistor to change it to manual. Google will tell you how.

 

The car will idle hunt while throwing the code 19.

 

So my idle won't sit right if I do this??

 

If that's the case, cut the jumper for auto/manual out and you're good to go. Google will tell you all about it.

 

so a socketed and chipped a/t ecu will throw an code unless converted? i had some guy tell me it doesnt matter if his p28 ecu was a/t or not when chipping it. it will work without a problem. was he full of it?

 

It does work without a problem, once you take the jumper out or skip all of the auto stuff in the code.

 

so i would assume skipping the auto stuff is something done with neptune or eCtune? say for an ecu chipped on crome, would removing the jumper be necessary as i dont think it has the option for auto or manual?

 

NepTune supports automatics. You need to remove the jumper (RP17) to make it manual.

 

10/4 thank you sir.

 

No problem
